Only time mine got hot enough to cause concern was on a day over 100ºF and I got stuck in construction traffic where I was at a complete stop most of the time and would only move a few yards at a time at about 5mph. That lasted for miles, just as I was about to shut down to let the bike cool we started to move and all was well.

I learned all I need to know about life by killing smart people and eating their brains.
Eat right ,Exercise ,Stay fit, Die Anyway!
